I certainly think that making users specify this at configure-time is
reasonable.  And like Mike, I see no reason to multilib it.  Just make
`--with-sjlj-exceptions' build with that kind of exceptions, instead
of the ordinary kind everywhere.  If you were already going to
multilib, you get the same multilibs -- but with the other kind of
exceptions.

My understanding is that enough people use this option to mean that we
should continue to support it.  So, I think doing this is probably a
necessary step.

Thanks,
